Description

Technical Field

[0001] This utility model relates to the field of smartwatch technology, and more specifically, to a smartwatch. Background Technology

[0002] As smartwatches become increasingly feature-rich, the number of integrated sensors, processors, and other electronic components is also growing, leading to increased heat generation during operation. Most current smartwatches employ a closed-loop design, with a tight space between the case and the movement, making heat dissipation difficult. Prolonged use can result in performance degradation, shortened battery life, and even component damage due to high temperatures, making heat dissipation a key factor affecting the stability of smartwatches. Furthermore, traditional smartwatches often use a fixed connection between the movement and the case. Repairing, cleaning, replacing the battery, or upgrading components requires specialized tools for disassembly, which is cumbersome and can easily damage the case or internal components. Ordinary users cannot perform maintenance themselves, increasing their time and financial costs and limiting the personalized modification and reuse of smartwatches.

[0003] Therefore, how to balance heat dissipation efficiency and ease of assembly / disassembly while ensuring structural stability has become a pressing technical challenge in current smartwatch design. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by proposing a smartwatch that aims to solve the problems of heat dissipation difficulties and inconvenient maintenance of existing smartwatches.

The locking device is connected to the first handle and the second handle respectively. The lock groove and the locking module are symmetrically arranged in two sets.

[0006] Furthermore, a heat dissipation vent is provided between the first chassis and the second chassis. The heat dissipation vent is located between each adjacent connecting column, and a plurality of connecting columns are arranged circumferentially between the first chassis and the second chassis.

[0007] Furthermore, the connecting seat is a hollow cylindrical structure, and the sidewall of the connecting seat matches the first groove.

[0008] Furthermore, both the first protrusion and the second protrusion are radial protrusions. The direction of the first protrusion is towards the axis of the connecting seat, and the direction of the second protrusion is opposite to that of the first protrusion. The sidewall of the first protrusion is connected to the sidewall of the second protrusion.

[0009] Furthermore, both the first handle and the second handle are provided with a column, a conical baffle and an arc plate. One end of the column is connected to the baffle, and the other end of the column is connected to the locking device through a traction line. The arc plate is provided on the side wall of the column, and the radius of the arc plate matches the radius of the locking groove.

[0010] Furthermore, the locking device is provided with a connecting plate and a snap-fit ​​plate. The traction line passes through the connecting plate and is connected to the snap-fit ​​plate. The side wall of the connecting plate is provided with a second groove, and a connecting rod is provided in the second groove. The side wall of the snap-fit ​​plate is provided with a connecting sleeve. The two sides of the connecting sleeve are symmetrically provided with third grooves. The connecting sleeve is sleeved on the connecting rod. The third groove is used to provide space for the connecting plate and the snap-fit ​​plate to rotate.

[0011] Furthermore, the snap-fit ​​plate is also provided with a fourth groove, in which a traction rod is disposed, and the traction rod is connected to the traction line.

[0012] Furthermore, the side wall of the snap-fit ​​plate is also provided with a snap claw, the bottom surface of which is a smooth inclined surface, and the snap claw engages with the connecting post.

[0013] Furthermore, the claw is provided with a fixed claw seat and a snap-fit ​​claw head, the fixed claw seat and the snap-fit ​​claw head are plugged into each other, and a plurality of springs are provided between the fixed claw seat and the snap-fit ​​claw head, the springs being used to provide elastic force to the snap-fit ​​claw head.

[0014] Furthermore, the end of the locking claw head is an arc surface, which is used for locking when in contact with the connecting post.

[0015] Compared with the prior art, the advantages of this invention are as follows: the watch movement is positioned between the placement module and the snap-fit ​​module, and the connection between the two forms a protective enclosed space for the watch movement, effectively isolating it from external impacts and vibrations and providing a stable working environment for the watch movement; in the placement module, the first and second bases are connected by connecting pillars to form a double-layer support structure, which improves the overall structural load-bearing strength and deformation resistance, and can disperse external forces to protect internal components; the lugs are connected to the side walls of the first and second bases respectively, ensuring the stability of the watch strap installation and evenly transmitting the force during wearing to the entire placement module, avoiding local stress concentration. The first groove, positioned circumferentially on the first base, is adapted to the connector of the snap-fit ​​module, achieving precise alignment between the placement module and the snap-fit ​​module, ensuring a tight connection between the two and reducing relative shaking during use. The first and second protrusions on the snap-fit ​​module enhance the compatibility with the placement module and the locking module. The symmetrical design of the locking module and the locking groove, through the evenly distributed locking force, makes the connection between the placement module and the snap-fit ​​module more secure, preventing loosening due to uneven force. At the same time, it provides a convenient structural foundation for subsequent disassembly and assembly, thus improving the overall structural stability, component protection, and connection reliability of the smartwatch.

[0027] like Figure 1-6 As shown, a preferred embodiment of the present invention provides a smartwatch, comprising: The watch movement 10, the placement module, the snap-fit ​​module and the locking module are connected. The watch movement 10 is located between the snap-fit ​​module and the placement module. The locking module is connected to the snap-fit ​​module. The placement module includes: a first base 201, a second base 202, a first groove 205, a lug 204, and a connecting post 203. The connecting post 203 is disposed between the first base 201 and the second base 202. The lug 204 is connected to the side wall of the first base 201 and the side wall of the second base 202 respectively. The first groove 205 is disposed in the circumferential direction of the first base 201. The snap-fit ​​module includes: a connector, a first protrusion 301, a second protrusion 302 and a locking groove 3021. The connector is connected to the first groove 205. The first protrusion 301 and the second protrusion 302 are both disposed on the connector, and the locking groove 3021 is embedded in the second protrusion 302. The locking module includes: a first handle 40a, a second handle 40b and a locking device 50. The first handle 40a and the second handle 40b are both disposed in the lock groove 3021. The locking device 50 is connected to the first handle 40a and the second handle 40b respectively. The lock groove 3021 and the locking module are symmetrically arranged in two sets.

[0028] It should be noted that in the placement module, the first base 201 and the second base 202 are connected by a connecting post 203, forming a double-layer support structure, providing a reliable mounting base for the watch movement 10; the lugs 204 facilitate the connection of the watch strap, ensuring a stable fit. The connecting seat of the snap-fit ​​module is compatible with the first groove 205 of the placement module, achieving precise alignment between the two. The first protrusion 301 on the connecting seat can directly press the watch movement 10 firmly onto the second base 202, effectively preventing the watch movement 10 from shaking or shifting during use, ensuring the normal operation of the watch. The locking module adopts a symmetrically distributed two-set design, and through the cooperation of the locking groove 3021 and the locking device 50, the placement module and the snap-fit ​​module are firmly fixed. During installation, rotating the first handle 40a and the second handle 40b allows for limited vertical movement within the locking groove 3021, providing the necessary range of motion for the locking device 50 and facilitating adjustment of the locking force. When locking is required, pulling the first handle 40a and the second handle 40b upwards and out of the locking groove 3021, followed by rotation, activates the locking device 50, firmly securing the placement module and the snap-fit ​​module. This ensures the stability of the overall structure, prevents loosening during use, simplifies the installation and disassembly process, and facilitates user replacement or repair of the movement 10, thereby enhancing the product's practicality and user experience.

[0029] In some embodiments of this application, a heat dissipation vent 206 is also provided between the first chassis 201 and the second chassis 202. The heat dissipation vent 206 is provided between each adjacent connecting column 203. A plurality of connecting columns 203 are arranged circumferentially between the first chassis 201 and the second chassis 202.

[0030] It should be noted that the heat dissipation vents 206, cleverly distributed between the first chassis 201 and the second chassis 202, are strategically positioned between adjacent connecting posts 203. Several connecting posts 203 are circumferentially arranged between the two chassis, ensuring the structural strength of the double-layer chassis while simultaneously creating efficient heat dissipation channels through the gaps between adjacent posts 203. When the smartwatch is running, the heat generated by the movement 10 can be quickly dissipated to the external environment through these vents 206, preventing heat accumulation between the movement 10 and the mounting module. This effectively reduces the risk of performance degradation due to high temperatures and extends the lifespan of the movement 10. Furthermore, the circumferentially distributed connecting posts 203 and heat dissipation vents 206 work together to optimize heat dissipation without compromising overall structural stability, further enhancing the reliability and durability of this invention.

[0031] In some embodiments of this application, the connecting seat is a hollow cylindrical structure, and the sidewall of the connecting seat matches the first groove 205.

[0032] It should be noted that the connector adopts a hollow cylindrical structure, and its sidewall matches the first groove 205. This design ensures a snug fit between the snap-fit ​​module and the placement module, while also reducing the overall weight of the structure to achieve precise docking, making the invention lighter and improving wearing comfort. The hollow structure also provides space for the arrangement of the watch movement 10, ensuring sufficient space for its placement. The sidewall of the cylindrical structure is adapted to the circumferential arrangement of the first groove 205, allowing the connector to bear force evenly within the first groove 205, further enhancing the stability of the connection between the snap-fit ​​module and the placement module, reducing wear caused by shaking during use, and extending the product's service life.

[0033] In some embodiments of this application, the first protrusion 301 and the second protrusion 302 are both radial protrusions. The direction of the first protrusion 301 is towards the axis of the connecting seat, and the direction of the second protrusion 302 is opposite to that of the first protrusion 301. The sidewall of the first protrusion 301 is connected to the sidewall of the second protrusion 302.

[0034] It should be noted that both the first protrusion 301 and the second protrusion 302 adopt a radial protrusion design, and their directions are opposite. This structural layout can form complementary force support on the connecting seat. The first protrusion 301 faces the axis of the connecting seat, which further enhances the clamping effect on the watch movement 10, forming a more stable clamping space with the second base 202, preventing the watch movement 10 from shifting radially. The second protrusion 302, facing the opposite direction, provides a reliable mounting base for the locking groove 3021, ensuring that the locking module can be stably connected to the snap-fit ​​module. Simultaneously, the sidewalls of the first protrusion 301 and the second protrusion 302 are connected, which not only improves the structural strength of the two protrusions themselves, preventing deformation under stress, but also makes the overall force distribution of the connecting seat more balanced, further enhancing the stability of the connection between the snap-fit ​​module, the placement module, and the watch movement 10, providing a strong guarantee for the reliable operation of the smartwatch.

[0035] In some embodiments of this application, both the first handle 40a and the second handle 40b are provided with a column 403, a conical baffle 401 and an arc plate 402. One end of the column 403 is connected to the baffle, and the other end of the column 403 is connected to the locking device 50 through a traction line 404. The arc plate 402 is provided on the side wall of the column 403, and the radius of the arc plate 402 matches the radius of the locking groove 3021.

[0036] It should be noted that the length of the column 403 is greater than the thickness of the locking groove 3021. The first handle 40a and the second handle 40b can move within the locking groove 3021, driving the entire locking device 50 to move. The structural design of the column 403, conical baffle 401, and arc plate 402 of the first handle 40a and the second handle 40b further improves the operational performance and stability of the locking module. The radius of the arc plate 402 matches the radius of the locking groove 3021, ensuring that the handles maintain a good fit when moving up and down within the locking groove 3021, avoiding jamming due to dimensional deviations, and ensuring smooth and unobstructed movement. The lower surface of the arc plate 402 and the upper surface of the second protrusion 302 are both rough surfaces, providing greater friction for their fit and maintaining the stability of the arc plate 402. The conical baffle 401 not only serves as a limit to prevent structural damage caused by excessive operation when pulling up the handle, but also becomes a key force point when pulling up the first handle 40a or the second handle 40b. Users can apply force to the conical baffle 401, making the force transmission more direct and efficient, facilitating the easy pulling out of the handle, and thus driving the locking device 50 to firmly fix the placement module and the snap-fit ​​module. This design optimizes the convenience of operation and enhances the reliability of the locking process through precise cooperation between structures, making the assembly and disassembly of smartwatches easier and smoother.

[0037] In some embodiments of this application, the locking device 50 is provided with a connecting plate 501 and a snap-fit ​​plate 502. The traction line 404 passes through the connecting plate 501 and is connected to the snap-fit ​​plate 502. The side wall of the connecting plate 501 is provided with a second groove 5011. A connecting rod 5012 is provided in the second groove 5011. The side wall of the snap-fit ​​plate 502 is provided with a connecting sleeve 5022. The two sides of the connecting sleeve 5022 are symmetrically provided with third grooves 5021. The connecting sleeve 5022 is sleeved on the connecting rod 5012. The third groove 5021 is used to provide space for the connecting plate 501 and the snap-fit ​​plate 502 to rotate.

[0038] It should be noted that the connecting plate 501 and the snap-fit ​​plate 502 of the locking device 50 form a rotatable structure through the cooperation of the connecting rod 5012 and the connecting sleeve 5022. This ensures the stability of the connection between the two and provides the locking device 50 with flexible operating space. The traction line 404 passes through the connecting plate 501 and connects to the snap-fit ​​plate 502, allowing the operating force of the first handle 40a and the second handle 40b to be accurately transmitted to the snap-fit ​​plate 502 via the traction line 404, causing the snap-fit ​​plate 502 to rotate around the connecting rod 5012. The second groove 5011 on the side wall of the connecting plate 501 provides a stable mounting base for the connecting rod 5012, while the connecting sleeve 5022 of the snap-fit ​​plate 502 is fitted onto the connecting rod 5012. Combined with the symmetrically arranged third grooves 5021 on both sides, sufficient space is reserved for relative rotation between the two, avoiding structural interference during rotation and ensuring smooth and efficient locking. Meanwhile, the length of the column 403 of the first handle 40a and the second handle 40b is greater than the thickness of the lock groove 3021. This design provides sufficient length margin for fixing the column 403 to the upper surface of the lower connecting plate 501, making the connection between the two more stable and reliable. It can transmit the operating force of the handle more directly and stably to the connecting plate 501, thereby driving the entire locking device 50 to move in tandem. This further improves the response sensitivity and structural integrity of the locking device 50, making the locking action more precise and powerful. It not only enhances the firmness of the connection between the placement module and the snap-fit ​​module, but also reduces the operating resistance through the coordinated cooperation of various components, optimizing the ease of disassembly and assembly and the structural reliability of the smartwatch.

[0039] In some embodiments of this application, the snap-fit ​​plate 502 is further provided with a fourth groove 5023, and a traction rod 5024 is provided in the fourth groove 5023. The traction rod 5024 is connected to the traction line 404.

[0040] It should be noted that the fourth groove 5023 on the locking plate 502 provides a dedicated installation space for the traction rod 5024, allowing it to be stably embedded within. The connection between the traction rod 5024 and the traction cable 404 further optimizes the force transmission path. When the first handle 40a and the second handle 40b drive the traction cable 404 via the column 403, the tension is first transmitted to the traction rod 5024, and then the traction rod 5024 acts on the locking plate 502, avoiding the potential instability issues that might occur when the traction cable 404 is directly connected to the locking plate 502. This design allows the tension of the traction cable 404 to drive the locking plate 502 to rotate around the connecting rod 5012 more smoothly and efficiently, ensuring consistent response and precise action of the locking device 50 during operation. This further improves the stability and reliability of the locking and unlocking process, while also extending the service life of the connection between the traction cable 404 and the locking plate 502, providing a stronger guarantee for the long-term stable use of the smartwatch.

[0041] In some embodiments of this application, the sidewall of the snap-fit ​​plate 502 is also provided with a snap-fit ​​claw 5029, the bottom surface of the snap-fit ​​claw 5029 is a smooth inclined surface, and the snap-fit ​​claw 5029 is snapped with the connecting post 203.

[0042] It should be noted that the claws 5029 on the side wall of the locking plate 502 are key components for achieving a stable connection between the locking device 50 and the placement module. Their engagement with the connecting post 203 enhances the connection strength between the locking module and the placement module. The bottom surface of the claws 5029 is designed as a smooth, inclined surface. This detail plays an important guiding and buffering role during installation: When installed, after the first handle 40a and the second handle 40b rotate, they move downwards within the locking groove 3021, and the tension of the traction line 404 decreases accordingly. The locking plate 502 below is in a relaxed state. At this time, the inclined surface of the claws 5029 moves downwards and contacts the side wall of the first chassis 201. The inclined structure converts the downward pressure into an outward thrust, causing the locking plate 502 to rotate outwards around the connecting rod 5012 at a certain angle. This prevents the claws 5029 from rigidly colliding or interfering with the first chassis 201, ensuring that the connecting seat can smoothly dock with the first groove 205. Once the connecting seat precisely aligns with the first groove 205, the end of the claw 5029 disengages precisely from the side of the first base 201. At this point, lifting the first handle 40a and the second handle 40b causes the traction line 404 to tighten and pull the locking plate 502 back to its original position. The claw 5029 then moves towards the connecting post 203 and precisely engages. Finally, rotating the first handle 40a and the second handle 40b completes the locking process. This design, through the guiding effect of the smooth inclined surface, simplifies the alignment process during installation, avoids jamming between components, and enhances the locking strength of the overall structure through the tight engagement of the claw 5029 and the connecting post 203. Simultaneously, the smooth treatment of the inclined surface reduces friction and wear during installation, extending the service life of components and making the assembly and disassembly of the smartwatch convenient, efficient, and reliable.

[0043] In some embodiments of this application, the claw 5029 is provided with a fixed claw seat 5025 and a snap-fit ​​claw head 5026. The fixed claw seat 5025 and the snap-fit ​​claw head 5026 are connected by an insertion. A plurality of springs 5028 are provided between the fixed claw seat 5025 and the snap-fit ​​claw head 5026. The springs 5028 are used to provide elastic force to the snap-fit ​​claw head 5026.

[0044] It should be noted that the jaw 5029 is composed of a fixed jaw base 5025 and a snap-fit ​​jaw head 5026, with several springs 5028 placed between them. This combination structure gives the jaw 5029 a telescopic and elastic adjustment capability. The fixed jaw base 5025 provides a stable mounting base for the snap-fit ​​jaw head 5026, while the elastic force of the springs 5028 ensures that the snap-fit ​​jaw head 5026 maintains appropriate pressure when snapping with the connecting post 203. This ensures that the snap-fit ​​jaw head 5026 and the connecting post 203 are engaged, preventing loosening gaps, and also that the buffering effect of the springs 5028 can offset slight vibrations during use, reducing wear caused by rigid contact. During disassembly, the elasticity of spring 5028 assists in the quick disengagement of the locking claw 5026 from the connecting post 203, making the unlocking process smoother. After rotating the first handle 40a and the second handle 40b into the lock groove 3021, the user can disengage the locking claw 5029 by moving the lower locking plate 502. This design not only enhances the reliability of the engagement between the locking claw 5029 and the connecting post 203, but also improves the durability of the components and the assembly error tolerance through the elastic structure, further optimizing the stability and ease of disassembly and assembly of the smartwatch.

[0045] In some embodiments of this application, the end of the snap-fit ​​claw 5026 is an arc surface 5027, which is used for snap-fit ​​when in contact with the connecting post 203.

[0046] It should be noted that the end of the locking claw 5026 is designed as a rounded surface 5027, a detail that further optimizes the locking effect with the connecting post 203. When the locking claw 5026 contacts the connecting post 203 under the elastic force of the spring 5028, the rounded surface 5027 can form a curved surface contact with the outer circumference of the connecting post 203 with a higher degree of fit. Compared with planar contact, this can better distribute the force and avoid component wear caused by local stress concentration. At the same time, the smooth transition characteristics of the rounded surface 5027 reduce the frictional resistance of the locking claw 5026 during engagement or disengagement with the connecting post 203. This facilitates the smooth engagement of the claw 5029 into the connecting post 203 and reduces relative wear between the two during disassembly, extending the service life of the component. In addition, the curved surface of the arc surface 5027 and the curved surface of the connecting post 203 can compensate for displacement by slight adjustment of the contact surface when the smartwatch is slightly shaken, maintain the stability of the locking, and avoid the locking loosening due to angular deviation, thus further improving the reliability and durability of the locking structure.

[0047] The working process of this utility model is as follows: During installation, the watch core 10 is first placed on the second base 202 of the placement module, and then the connecting seat of the snap-fit ​​module is aligned with the first groove 205 in the circumferential direction of the first base 201 of the placement module and docked. At this time, the first protrusion 301 on the connecting seat will press the watch core 10 tightly on the second base 202, thereby achieving the initial fixation of the watch core 10. Subsequently, the first handle 40a and the second handle 40b located in the locking groove 3021 of the locking module are operated. First, the handles are rotated to move up and down within the locking groove 3021 to adjust their position. Then, the handles are pulled up and removed from the locking groove 3021 and rotated. The handle column 403 drives the traction line 404, which transmits the force to the locking plate 502 of the locking device 50. This causes the locking plate 502 to rotate around the connecting rod 5012 of the connecting plate 501. The claws 5029 on the side wall of the locking plate 502 move toward the connecting post 203 of the placement module and engage with it. The two sets of symmetrically arranged locking modules form a balanced locking force, which firmly fixes the placement module and the locking module, completing the overall installation. During disassembly, rotate the first handle 40a and the second handle 40b in the opposite direction and move them into the locking groove 3021. The tension of the traction line 404 decreases, and the locking plate 502 is in a relaxed state. The user can then pull the lower locking plate 502 to disengage the claw 5029, thereby enabling the removal and maintenance of the watch movement 10.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
